• It is the third single off of his fifth studio album Tickets to My Downfall. The song, the third to feature a pop punk sound, features guest vocals by
Blackbear.
• The song was described as pop punk, but as a modern take on it, rather than the "classic" form of the genre. Publications described it as a "guitar-laden" song with the two singers covering the complications of relationship breakups and rebound relationships.
